Ambulatory aquatic veterinary medicine allows examination of a patient's environment and identification of potentially sick animals. Common clients to use ambulatory service are owners of large koi and aquaculture facilities, but any aquatic animal owner could benefit from on-site services. This practice limits stress from handling and transporting large or critically sick or injured aquatic animals. Additional skills must be practiced to attain proficiency in capturing potential patients. Most diagnostics are available to practitioners in an ambulatory setting and follow-up care must be thoroughly discussed with clients.
